AUTOMATIC DOOR-SIGN.

Specification of Letters Patent.

Patented Aug. 7, 1906.

Application filed June 3,1905. Serial No. 263.590.

To all whom it may concern:

Be it known that I, EnNsT H. W. STAHL- HUTH, a citizen of the UnitedStates, residing at Columbus, in the county of Bartholomew and State ofIndiana, have invented a new and useful Improvement in Automatic D oor-1,

Signs, of which the following is a specification.

This invention relates generally to signs, and more particularly to anautomatic advertising-sign adapted to be attached to a swinging door,the object being to provide a device of such construction and soarranged that when the door is opened and closed the position of thesign will be shifted so as to expose different portions thereof, and byapplying different advertising-matter to said portions it is obviousthat as the door is opene and closed the advertisement will be changed,thereby attracting more attention than if the said advertisementremained stationary.

With this object in view my invention conessentially, of a sign-plateadapted to be pivoted to a door or other swinging object and having arod pivotally connected thereto, the opposite end of said rod beingadapted to be connected to the door-frame or other fixed object, so thatas the door is opened and closed the rod will cause the sign-plate toturn upon its' pivot, displaying alternately the opposite ends thereof.

The invention consists also in certain details of construction andnovelties of combination, all of which will be fully describedhereinafter, and pointed out in the claim.

In the drawings forming a part of this specification, Figure 1 is a viewshowing the practical application of my invention. Fig. 2 is a detail'view showing the sign-plate arranged to display one of theadvertisements. Fig. 3 is a detail view showing an opposite end of thesign-plate displayed. Fig. 4 is a sectional view of the door andattached parts when the said door is closed. Fig. 5 is a similar viewshowing the position the parts assume when the door is opened.

Referring to the drawings, A indicates a door, and B the frame to whichthe door is hinged.

C indicates an advertising sign-plate,which is preferably formed withtwo lobes, each beadapted to receive an advertisement, which may beprinted or pasted thereon, and pivotally connected to this sign-plate atsubstantially the center of one edge is a rod D.

The sign-plate C is pivotally connected to the door by means of apivot-pin E, and the opposite end of the rod D is connected to ascrew-eye F, which is screwed into the doorframe B in such a positionthat when the door is opened the rod will turn the sign-plate so as tobring into view the opposite end, it being understood that thesign-plate is attached to a door having a glass panel and is pivoted tothe solid portion of the door just below the lower end of the glasspanel, so that either lobe of the plate can project a sufficientdistance above the solid portion of the door to properly display theadvertising-matter. is obvious, therefore, as the door opens oneadvertisement is displayed and that as the door is closed the otheradvertisement is disary.

Having thus fully described my. invention, what I claim as new, anddesire to secure by Letters Patent, is'

The combination with a door having a transparent panel therein, of anelongated plate eccentrically pivoted to the door adja cent said panel,a portion of said plate being visible through the said panel, a rodpivotally connected to the door-frame at one end and pivotally connectedat the opposite end to the said plate at a point adjacent the pivotalpoint of the plate, and adapted to automatically bring alternateportions of the plate into alinement with the panel as the do or isopened and closed.
